HOLLYWOOD - British actress Sienna Miller horrified Hollywood after she was photographed behaving in a "loud, childish" fashion at Vanity Fair's post-Oscar bash last month.The images, which will be published in the May issue of Vanity Fair, show Miller cavorting drunkenly with bit-part actress Tara Summers, having her foot nibbled by her pal and hitching up her dress while waving her bare legs in the air.

Far from being impressed by her antics, the guests, mainly studio executives and producers, collectively cringed at Miller's embarrassing faux-pas--planting a question mark over her fledgling Hollywood career.

A leading Hollywood producer tells British newspaper the Mail on Sunday, "It's one thing to be gossiped about, but it's quite another to have pictures of yourself in that kind of clinch plastered all over a magazine.

"Hollywood is notoriously straight-laced when it comes to the behavior of a young star.

"This is an industry town. Actresses who expect to be taken seriously simply don't get drunk and behave like this in public."

An eyewitness branded her "loud and childish," adding, "Everyone was talking about how Sienna was totally over-the-top. These pictures have seriously damaged her reputation."

However, Miller's spokeswoman denies any raucous behavior, insisting, "They have just wrapped a film together and they were just sitting next to each other at a party. Nothing more than that.

"We've had no complaints."

How stupid is it to go to a leading magazine's party, get drunk and act like an idiot? You expect this won't get into the magazine itself?? I can't wait to see the article and pictures. Apparently it will be in the "Green" issue.

^i agree, this was bound to happen.
she was always toooo much out there just for the attention, and nothing else. like in every pic you see of her, she's dancing and playing for the cameras, just to get as much attention as possible. there's just no substance to it.......

i'm confused. . . it was a party. wasn't she just partying? anyway, i have to see the pictures to say anything else, but i am guessing that she wasn't doing anything worse than what any of the other hollywood starlets do nightly.

I don't think she should be flamed for this that much either,
but most starlets do it at dance clubs, not the Vanity Fair Oscar Party.

why does everybody seem to want her to fail-she seems like a perfectly nice person to me, and yet everybody is so harsh and cruel about her....I mean maybe she's immature, but she doesn't seem stuck up and rude, wouldn't that be worse?

AMEN!

Hollywood is "the natural Paparazzi habitat" and anyone who is only slightly famous needs to expect to be photographed any second - especially Sienna WHO BECAME A STYLE-ICON FROM PAPARAZZI PICS has no right to complain now!

As much as I don't condone her behavior, this really isn't anything more people like Lindsay Lohan do every night. Might not be a good thing, or a smart thing, but unfortunately, that's life. However, it's also life that after behaving that way at Vanity Fair's after party, there is real evidence of her acting like this. This is one of those "acceptable if you don't get caught" type of things, which is so hypocritical. But it seems like that is how the game goes now.
